Object tracing test case fails in NRF boards

[spoorthik]

The test case in tests/kernel/obj_tracing fails for NRF board due to an extra semaphore than the expected number.

Steps to reproduce:

• cd <ZEPHYR_BASE>/tests/kernel/obj_tracing
• mkdir build && cd build && cmake -DBOARD=nrf51_pca10028 ..
• /nrfjprog/nrfjprog --eraseall -f nrf51
• /nrfjprog/nrfjprog --program build/zephyr/nrf52_pca10040/zephyr.hex -f nrf51
• /nrfjprog/nrfjprog --reset -f nrf51
